The first quake hit a remote area around the coastal town of Nabire on Friday.
The quake registered six point nine on the Richter scale and damaged roads and communication facilities.
At least thirty people are now known to have been killed as buildings and homes collapsed -- hundreds of others have been injured.
On Saturday, a second quake hit measuring seven point one on the Richter scale hit relatively close to the town setting off panic among the residents.
